strcmp, strncmp - compare two strings
SYNOPSIS
#include
int strcmp(const char *s1, const char *s2);
int strncmp(const char *s1, const char *s2, size_t n);
DESCRIPTION
//描述
The strcmp() function compares the two strings s1 and s2. It returns an integer less than, equal to, or greater than zero if s1 is found, respectively, to be less than, to match, or be greater than s2.
//strcmp这个函数是用来比较字符串s1和s2。如果s1存在它返回一个整型变量，如果返回值小于0那么s1小于s2,如果返回值等于0那么 //s1等于s2,如果返回值大于0那么s1大于s2.
The strncmp() function is similar, except it only compares the first (at most) n characters of s1 and s2.
//函数strncmp函数与其相似，除了在s1和s2之间比较n个字符。
RETURN VALUE
//返回值
The strcmp() and strncmp() functions return an integer less than, equal to, or greater than zero if s1 (or the first n bytes thereof) is found, respectively, to be less than, to match, or be greater than s2.
//strcmp函数和strncmp函数都返回一个整型变量，如果s1存在，相对应的整型变量小于或等于或大于0就对应于小于或等于或大于 //s2。
